If I could do it all again, I'd study a lot more math in University and probably end up focusing on something like Audio DSP. I think it's a pretty safe career choice since it's hard self learn compared to a lot of other fields, meaning competition is less. And if you are good, companies will happily pay you to learn tech of the week.
